1252 Navigation bar node menu button click can fail [6822]

[chrisjj]

1 Click on a node menu (down arrow) button on the Navigation bar (node menu appears)
2 Click on a track in the track list (node menu disappears)
3 Click on the same button as #1

Expected: node menu appears
Observed: no effect

The same happens in the cases of
2 Press ESCAPE
2 Click main menu bar item
2 Click search bar
and probably others.
